The CO₂ Connection: A Hidden Clue to Indoor Air Quality with Dr. Allison Bailes

Can an invisible gas reveal hidden issues with your home's air quality?

Building scientist Dr. Allison Bailes makes a complicated topic accessible as he breaks down the seven-part layered approach to keeping your indoor air in tip-top shape. Learn the three strategies for whole-house ventilation and the surprising way carbon dioxide (CO₂) can reveal how well your home is ventilated. Find out which indoor air monitors are the most useful and whether “Build tight, ventilate right” is the correct strategy for your next home build. Come away with a better understanding of your own home’s ventilation processes as you learn about source control, filtration, air tightness, and more.

If you’ve been looking for a consumer-friendly explanation about your home’s ventilation, this is the episode for you!
